Important Points

Terminology	Related Aspects	Justification
Biogeochemical cycles	Nutrient cycles	Biogeochemical cycles represent the movement of elements, such as carbon, nitrogen, oxygen, and so on, through living (bio-) and non-living (-geo-) parts of an ecosystem in a cyclic manner. These are equivalent to nutrient cycles, providing a flow of vital nutrients in ecosystems.
Flow of Energy	Law of Thermodynamics	The flow of energy in an ecosystem complies with the law of thermodynamics. The first law represents energy conservation (energy can neither be created nor destroyed, only transformed), while the second law represents the inefficiency of energy transfer (some energy is always lost as heat during energy transfer).
Biomass	Ecosystem productivity	Biomass refers to the total mass of organisms in a specific area or volume. It is directly related to ecosystem productivity, as it represents how efficiently organisms convert energy (usually sunlight) into biomass (organic matter).
Food chain	Trophic Pyramid	A food chain demonstrates a sequence of organisms through which nutrients and energy pass as one organism eats another. This is graphically represented in the trophic pyramid or ecological pyramid, showing the energy or biomass present at each trophic level.
